#!/bin/bash
ts=$(date +%Y%m%d-%H%M%S)
log="gcp-licenses-logs-$ts"
>$log
while read -r project; do
    echo "Project: $project" | tee -a $log
    gcloud compute instances list --project $project --format="table[no-heading](name,zone.basename())" > instances.list
    while read -r instance zone; do
        gcloud compute instances describe $instance \
        --project $project \
        --zone $zone \
        --format="table[no-heading](name,zone.basename(),disks[0].licenses[0].basename())" | tee -a $log
    done < instances.list 
done < projectIds.txt

GCP List Snapshots Older Than

Here’s how to list snapshots older than a certain date. In this example, it’s 1 year.

gcloud compute snapshots list --project $project --filter="creationTimestamp < '2022-06-15'" --format="value(name)"

GCP Old Scheduled Snapshots

Here’s how to list GCP Scheduled Snapshots older than 14 days. projectIds.txt contains a list of projects.

#!/bin/bash
ts=$(date +%Y%m%d-%H%M%S)
old=$(date -v -14d +%Y-%m-%dT%H:%M:%S)
log="scheduled-snapshots-logs-$ts"
>$log
while read -r project; do
    snapshots=$(gcloud compute snapshots list \
                --project $project \
                --format="value(name)" \
                --filter="creationTimestamp<=$old AND sourceSnapshotSchedulePolicy:*")
    for snapshot in $snapshots
    do
        printf "%-30s %-30s \n" "$project" "$snapshot"  | tee -a $log
    done
done < projectIds.txt
